An atom is invisible, much tinier than a minuteYet atoms make up the world and everything in itA cloud of electrons so swift and intenseSurrounding a nucleus tiny and denseDeep down at the center of it allA nucleus—extremely very small

Johnstone Stoney invented my new electric nameErnest Rutherford and Niels Bohr then brought me fameThey guessed within the atom my inner and outer gameYou’ll agree what they did for me, I’ll do it for them the same
